Introduction
This chapter describes the PXI-1050, lists what you need to get started,
describes the optional equipment, and explains how to unpack the
PXI-1050 chassis.
About the PXI-1050 Chassis
Thank you for purchasing the National Instruments PXI-1050 chassis. This
chassis integrates a high-performance 8-slot PXI subsystem with a 4-slot
SCXI subsystem to offer a complete solution for signal conditioning
applications. The PXI section of the chassis accepts an embedded
controller and a wide variety of peripheral modules (such as multifunction
I/O, digital I/O, and instrument modules). The four SCXI slots integrate
signal conditioning modules into your PXI system. These modules provide
analog and digital input conditioning, isolation, and other functions. The
PXI-1050 is ideal for applications where rack-mount space is limited
because it combines the computer, plug-in devices, and signal conditioning
in a single chassis. You can daisy-chain additional SCXI chassis to the
PXI-1050 to build very high channel-count systems.

Introduction
Software Programming Choices
You have several options to choose from when programming your National
Instruments DAQ and SCXI hardware. You can use National Instruments
application software, NI-DAQ, or register-level programming.
National Instruments Application Software
ComponentWorks contains tools for data acquisition and instrument
control built on NI-DAQ driver software. ComponentWorks provides
a higher-level programming interface for building virtual instruments
through standard OLE controls and DLLs. With ComponentWorks, you
can use all of the configuration tools, resource management utilities, and
interactive control utilities included with NI-DAQ.
LabVIEW features interactive graphics, a state-of-the-art user interface,
and a powerful graphical programming language. The LabVIEW Data
Acquisition VI Library, a series of VIs for using LabVIEW with National
Instruments DAQ hardware, is included with LabVIEW. The LabVIEW
Data Acquisition VI Library is functionally equivalent to NI-DAQ
software.
LabWindows/CVI features interactive graphics, state-of-the-art user
interface, and uses the ANSI standard C programming language. The
LabWindows/CVI Data Acquisition Library, a series of functions for using
LabWindows/CVI with National Instruments DAQ hardware, is included
with the NI-DAQ software kit. The LabWindows/CVI Data Acquisition
Library is functionally equivalent to the NI-DAQ software.
VirtualBench features virtual instruments that combine DAQ products,
software, and your computer to create a stand-alone instrument with the
added benefit of the processing, display, and storage capabilities of your
computer. VirtualBench instruments load and save waveform data to disk
in the same forms that can be used in popular spreadsheet programs and
word processors.

Introduction
NI-DAQ Driver Software
The NI-DAQ driver software is included at no charge with all National
Instruments DAQ hardware. NI-DAQ has an extensive library of functions
that you can call from your application programming environment. These
functions include routines for analog input (A/D conversion), buffered data
acquisition (high-speed A/D conversion), analog output (D/A conversion),
waveform generation, digital I/O, counter/timer operations, SCXI, PXI
Trigger Bus (RTSI), self-calibration, messaging, and acquiring data to
extended memory.
NI-DAQ also internally addresses many of the complex issues between the
computer and the plug-in board, such as programming interrupts and DMA
controllers. NI-DAQ maintains a consistent software interface among its
different versions so that you can change platforms with minimal
modifications to your code. Whether you are using conventional
programming languages or National Instruments application software, your
application uses the NI-DAQ driver software, as illustrated in Figure 1-1.

Introduction
Register-Level Programming
Another option for programming any National Instruments DAQ hardware
is to write register-level software. Writing register-level programming
software can be very time-consuming and inefficient and is not
recommended.
Even if you are an experienced register-level programmer, consider using
National Instruments application software to program your National
Instruments DAQ hardware. Using National Instruments application
software is easier than and as flexible as register-level programming and
can save weeks of development time.
Optional Equipment
National Instruments offers a variety of products to use with your
PXI-1050 chassis, including cables and other accessories, as follows:
•
Cables and cable accessories, shielded and ribbon
•
Shielded and unshielded 68- and 100-pin screw terminals
•
SCXI modules and accessories for isolating, amplifying, exciting,
and multiplexing signals for relays and analog output
•
PXI modules and accessories for multifunction I/O and
instrumentation
For more specific information about these products, refer to your National
Instruments catalog or call the office nearest you.

•
Install SCXI modules that are each dedicated to conditioning signals
for only a single DAQ device (for example, in parallel mode), or that
operate independently and only use the SCXI subsystem as a power
source and/or container. You can use the chassis this way in addition to
or instead of one of the first three methods.
PXI Subsystem Backplane Overview
The following sections describe the PXI subsystem backplane.
Interoperability with CompactPCI
The PXI backplane is interoperable with PXI-compatible products and
standard CompactPCI products. This is an important feature, because many
PXI-compatible systems may require components that do not implement
PXI-specific features.
For example, you may want to use a standard CompactPCI network
interface card in a PXI chassis. The signals on the PXI-1050 backplane
P1 connector meet the requirements of the CompactPCI specification for
both the peripheral and system modules. The PXI-specific signals are
located on the P2 connector and are found only on the signals that are
reserved or not used in the CompactPCI 64-bit specification. Therefore,
all modules that meet the CompactPCI 64-bit specification requirements
will function in the PXI-1050.

Introduction
System Controller Slot
The System Controller slot is located in Slot 1 of the chassis as defined by
the PXI specification. It has three controller expansion slots, which are
used for system controller modules wider than one slot. As defined in the
PXI specification, these slots allow the controller to expand to the left so it
does not use up peripheral slots.
Peripheral Slots
The PXI-1050 has seven peripheral slots located in Slots 2 through 8. You
can use PXI modules in peripheral slots to add functionality to the PXI
subsystem not already provided by the system controller. Examples of PXI
peripheral modules are multifunction I/O, digital I/O, and instrument
modules. Some peripheral slots also have special capabilities, such as the
Star Trigger slot and the SCXI Control slot, which are explained in the
following sections.
Star Trigger Slot
The Star Trigger slot is located at Slot 2. This slot has a dedicated trigger
line between each peripheral slot (refer to Figure 1-4) and is intended for
modules with Star Trigger functionality to provide individual triggers to all
other peripherals. However, if you do not require advanced trigger
functionality, you can install any standard peripheral module into this slot.
Local Bus
The PXI backplane local bus is a daisy-chained bus that connects each
peripheral slot with its adjacent left and right peripheral slots, as shown in
Figure 1-4.
For example, a given peripheral slot’s right local bus connects to the
adjacent slot’s left local bus and so on. Each local bus is 13 lines wide and
can pass analog signals between modules or provide a high-speed
side-band communication path that does not affect the PXI bandwidth.
Local bus signals may range from high-speed TTL signals to analog signals
as high as 42 V. Initialization software keys adjacent modules to prohibit
the use of incompatible devices. This software uses the configuration
information specific to each peripheral module to evaluate compatibility.
This method is a flexible way to define local bus functionality that is not
limited by keying hardware.

SCXI Connection
Slot 8 of the PXI backplane has connections for a PXI peripheral module
to control the SCXI subsystem. These connections use the available
local bus right pins (PXI_LBR0:12). The SCXI connection passes
communication, timing, and analog signals between the SCXI backplane
and the PXI module in Slot 8.
Trigger Bus
The eight PXI trigger lines are bused to each slot. You can use the trigger
lines in a variety of ways. For example, you can use triggers to synchronize
the operation of several different PXI peripheral modules. In other
applications, one module can control carefully timed sequences of
operations performed on other modules in the system. Modules can
pass triggers to one another, allowing precisely timed responses to
asynchronous external events the system is monitoring or controlling.

Introduction
System Reference Clock
The PXI-1050 supplies the PXI 10 MHz system clock signal (PXI_CLK10)
independently to each peripheral slot. An independent buffer (having a
source impedance matched to the backplane and a skew of less than 1 ns
between slots) drives the clock signal to each peripheral slot. You can use
this common reference clock signal to synchronize multiple modules in a
measurement or control system. You can drive PXI_CLK10 from an
external source through the PXI_CLK10_IN pin on the P2 connector of the
Star Trigger slot. (Refer to Table B-4, P2 (J2) Connector Pinout for the
Star Trigger Slot.) Sourcing an external clock on this pin automatically
disables the backplane 10 MHz source.

This chapter describes how to prepare and operate your PXI-1050 chassis.
Mounting Information
The PXI-1050 is designed to operate on a bench or in an instrument rack.
Determine how you want to use your PXI-1050 and follow the appropriate
installation instructions.
Apertures in the rear, along both sides, and on top of the chassis facilitate
power supply and module cooling. Air enters through filters and fan inlets
located in the lower rear of the chassis and exits through the upper side
sections and through the top. Place your PXI-1050 on a bench top or in an
instrument rack so that the fans (air inlets) and the air outlet apertures along
both sides of the chassis have adequate ventilation. Keep other equipment
a minimum of 3.0 in. (76.2 mm) away from the air inlets and outlets.
Install your chassis for easy access to the rear panel. This simplifies the air
filter replacement.
Rack-mount applications require the optional rack-mount kit available
from National Instruments. Refer to the rack-mount kit documentation to
install your PXI-1050 in an instrument rack.
Chassis Configuration
Chassis configuration involves selecting an SCXI subsystem address,
line voltage, and fuse value, described briefly in the following sections.
SCXI Subsystem Address Selection
Note Unless you are using multiple chassis and need to configure one or more SCXI
chassis for a different address, you can skip this section. The SCXI subsystem will have the
factory-default address of 0.
© National Instruments Corporation

NI PXI-1050 User Manual
Chapter 2
Installation and Configuration
You can configure the SCXI subsystem for one of 32 different addresses so
that you can connect multiple SCXI chassis to the same control source. The
five switches on the front panel of Slot 0 determine the chassis address.
Switches one through five represent the values 1, 2, 4, 8, and 16
respectively, when set to the ON position. When set to the OFF position,
their value is 0. The chassis address is the sum of the switch values.
Figure 2-1 shows examples of both the factory-default setting of the chassis
address 0 and the switch setting for chassis address 19.

Line Voltage Selection and Fuse Values
The voltage selection wheel and fuse should be correct for operation
in your geographical region (the -0x extension of the kit part number
corresponds to your geographical region). Check the voltage on the voltage
selection wheel to ensure that you have the correct voltage setting and fuse.
The PXI-1050 chassis can operate with line voltages of 100, 120, 220,
and 240 VAC. The voltage selection wheel in the power entry module
determines the voltage for which the chassis is configured. Identify the
operating voltage by looking at the number on the power entry module
when the selection wheel door is closed. The fuse is a 5 by 20 mm
SLO-BLO type, which has a current rating relative to the operating voltage.
Table 2-1 shows the proper voltage selection and fuse ratings for different
geographical regions.
For continued protection against fire, replace fuses only with fuses of the same
type and rating.

Maintenance
This chapter describes basic maintenance procedures for the PXI-1050
chassis.
Maintenance Procedures
Service Interval
Clean the chassis fan filters at a maximum interval of six months.
Depending upon the amount of use and ambient dust levels in the operating
environment, the filters may require more frequent cleaning.
Clean dust from the chassis exterior and interior as needed, based on the
operating environment. Periodic cleaning increases reliability.
Preparation
The information in this section is designed for use by qualified service
personnel.
Many components within the chassis are susceptible to static discharge damage.
Service the chassis only in a static-free environment. Observe standard handling
precautions for static-sensitive devices while servicing the chassis. Always wear a
grounded wrist strap or equivalent while servicing the chassis.
Caution
Cleaning
Cleaning procedures consist of cleaning the exterior and interior of the
chassis and fan filters. Refer to your PXI module documentation for
information on cleaning the individual CompactPCI or PXI modules.
Always power off the chassis and disconnect the power cable before cleaning or
servicing the chassis.
Caution
Interior Cleaning
Use a dry, low-velocity stream of air to clean the chassis interior. Use a
soft-bristle brush for cleaning around components.

NI PXI-1050 User Manual
Chapter 3
Maintenance
Exterior Cleaning
Clean the exterior surfaces of the chassis with a dry lint-free cloth or a
soft-bristle brush. If any dirt remains, wipe with a cloth moistened in a mild
soap solution. Remove any soap residue by wiping with a cloth moistened
with clear water.
Cautions Do not use abrasive compounds on any part of the chassis.
Avoid getting moisture inside the chassis during exterior cleaning.
Do not wash the front- or rear-panel connectors or switches. Cover these components while
cleaning the chassis.
Do not use chemical cleaning agents: they may damage the chassis. Avoid chemicals that
contain benzene, toluene, xylene, acetone, or similar solvents.
PXI Subsystem Fan Filter Cleaning
To easily remove the chassis cooling filters from the rear of the chassis,
remove the plastic housing attached to each fan.
To clean the fan filters, wash them in a mild soap solution and then vacuum
or blow air through them. Rinse the filters with water and allow them to dry
before reinstalling them onto the chassis.
SCXI Subsystem Fan Filter Cleaning
The fan on the rear of the SCXI subsystem cools the SCXI subsystem and
its modules. To keep the fan effective, the fan filters must be clean. Dust
and dirt accumulation reduces airflow, which makes the inside of the
chassis hotter, shortening the life of the chassis and modules. Complete the
following steps to clean the fan filters:
1.
Power off the chassis.
2.
Remove the power cable from the power-entry module.
3.
Place the chassis face down on a flat surface so that the fan is on top.
If the chassis is so heavily cabled that you cannot practically place it in
this position, leave the chassis as it is but be careful to support the fan
during removal and reinstallation to prevent breaking the fan wires.
To remove the fan filter, remove the four screws that secure the fan and
filter to the rear of the chassis. When removing the last screw, be
careful to hold the fan to prevent breaking the fan wires.

Maintenance
4.
Clean the fan filter by moving the filter around under a gentle stream
of cold tap water until all the dust has been removed. Dry the filter.
5.
Replace the fan filter by aligning the fan and filter with the fan holes,
making sure that the label side of the fan is face down. Reinstall the
four screws and make sure the assembly is secure.
Resetting the AC Main Circuit Breaker
If your PXI subsystem encounters an over-current condition, the circuit
breaker located on the rear panel will trip to prevent chassis damage. Refer
to Figure 1-2, Front View of the PXI-1050 Chassis, and Figure 1-3, Rear
View of the PXI-1050 Chassis, as you complete the following steps:
1.
Turn off the PXI power switch.
2.
Depress the circuit breaker to reset it.
3.
Turn on the PXI power switch.
If the circuit breaker trips again, complete the following steps:
1.
Turn off the PXI power switch.
2.
Remove all modules from the chassis.
3.
Depress the circuit breaker to reset it.
4.
Turn on the power switch and verify that the circuit breaker does
not trip.
5.
Verify that your PXI-1050 can meet the power requirements of your
CompactPCI or PXI modules. Overloading the chassis can cause the
breaker to trip. Refer to Appendix A, Specifications, for power
requirements.
6.
The over-current condition that caused the circuit breaker to trip may
be due to a faulty CompactPCI or PXI module. Refer to your module
documentation to troubleshoot your modules.

SCXI Subsystem Backplane Fuse Replacement and Check
In addition to the power entry module fuse, the analog supply lines on the
backplane are fused at 1.5 A. The fuse manufacturer is Littelfuse, part
number 251 01.5.
If you are going to make your own modules, fuse your module at 250 mA
to avoid blowing the backplane fuses. Fusing your module also better
protects your module because a failure can result in a large amount of
current drawn, but not enough to blow the backplane fuses.
The backplane fuses are located behind the SCXI subsystem fan.
Complete the following steps to check or replace fuses:

Star Trigger slot
This slot is located at Slot 2 and has a dedicated trigger line between each
peripheral slot. Use this slot for a module with Star Trigger functionality
that can provide individual triggers to all other peripherals.
System Controller
A module configured for installation in Slot 0 of a VXIbus mainframe.
This device is unique in the VXIbus system in that it performs the VMEbus
system controller functions, including clock sourcing and arbitration for
data transfers across the backplane. Installing such a device into any other
slot can damage the device, the VXIbus backplane, or both.
